wideband sensor wiring

Hello !!! i need some help with a wideband sensor conection to my efie
My cars sensor is an NTK JAPAN type with 5 wires.When the engine is running i have:
1.blue 13.20v
2.yellow. 3.85-4.15v
3.white. 3.30-4.00v
4.grey 4.25v
5.black 3.80v
Do i need to conect the yelow or the grey???
please HELP!!!

ok i think i got it ....i install the Efie from fuelsaver-mpg.
This is an enhaser for the wideband and the narowband for my car.
I managed to find at last the wright wire(i believe so),it has to be the grey one ...its the one that has 4.2v constant wile engine is running at idle .
it has to be that because when i conect it to the efie and tuen the cnob clockwise it can almost turn off the engine so it does something ...
As for the sensor after the catalytic converter this is a narowband and i have it also conected to the efie ..this is trimed at 260mv from the efie.
Today i did some klm with the efie on and the hho on .
Traveling with 80kph at some points at a relatively flat hiway the engine seamed a litle underpowered so i trimed the wideband sensor to the point that it run ok .
Im know at the testing period
Also i changed the NaOH with KOH and i run it at 15A ..no pwm
im geting about 0.6-0.7 liters off gas per minute and my car is 1.4liter 100hp
Do i need more hho??
Does the ECU need time or maybe a big travel to adapt with the knew situation....antil now i used hho without efie .

That should be enough HHO but some time it requires more or less. Why did you change to KOH?

You must reboot the ECM after you make changes. I would do that a few time during the first month maybe once every two weeks depending on how much you drive or even weekly. Disconnect the battery terminals and leave them off for a few minutes. I touch the terminals together but this is not necessary. This has helped some vehicles maintain the settings. But has not made any difference in some.
